Bay of Bengal. These last records, however, except one from Ceylon, refer to prO- 

 tntUS. 



In a memoir on the recent crinoids of Australia published in 1911, and in another 

 paper on the crinoids of southwestern Australia published in the same year, I referred 

 Hartlaub's specimen from Torres Strait to S. monacantha (=protectus). 



In 1912 Hartlaub compared a specimen of Antedon monacantha ( = S. protectus) 

 from the Marshall Islands with his original specimens from Mortlock Island and Torres 

 Strait. 



In a paper on the crinoids of the Hamburg Museum published in 1912 1 said that 

 the specimen recorded by Hartlaub from Torres Strait appears to be nearer S. indica 

 than S. monacantha ( = protectus) . 



In my memoir on the crinoids of the Indian Ocean published in 1912 I gave a 

 s\ nimymy of S. indica and a list of the localities from which the species is known. 

 The synonymy includes some references that should have been placed under S. mona- 

 cantha (=protectus). Of the localities given, Madagascar, the Seychelles, Rodriguez, 

 Farquhar Atoll, and Ceylon (in part) refer to S. indica, and Mublas (=Muhlos), 

 Male, Hulule, and Muhlos, Maldives, Ceylon (in part), and Tuticorin refer to S. pro- 

 tectus. In a short paper on a small collection of recent crinoids from the Indian Ocean 

 published at Calcutta in the same year S. indica was recorded from latitude 8°51'30" 

 N., longitude 81°11'52" E., in 28 fathoms; the two specimens on which this record 

 was based are in reality S. protectus. 



In a paper on the crinoids of the British Museum published in 1913 I noted that 

 I had examined Smith's type specimen of Comatula indica, and also another specimen 

 from the Seychelles taken >n 34 fathoms. I also recorded as S. indica a number of 

 specimens from the Maldives and Tuticorin, which represent in reality S. protectus. 



In 1915 Dr. Hubert Lyman Clark described a new species, Lamprometra calli- 

 /ifcha, w Inch was based upon a specimen that he had personally collected at Mer Island 

 in Torres Strait in 1913, and in another paper he included S. indica in a list of the crin- 

 oids of Ceylon. 



In a paper on the distribution of the recent crinoids on the coast of Australia pub- 

 lished in 1915, 1 included Hartlaub's specimen from Torres Strait under S. monacantha 

 (=protectus). 



In my report upon the unstalked crinoids of the Siboga expedition published in 

 1918 I gave a synonymy of S. indica and recorded and described a specimen from sta- 

 tion 301 that is in reality S. protectus. I said that this specimen appears to be identical 

 with Hartlaub's specimen of monacantha from Torres Strait; it also agrees with speci- 

 mens of indica (=protectus) at hand from Ceylon and with others from Madagascar, 

 though the size is somewhat greater. I added that there can be little doubt that the 

 specimen taken by Dr. H. L. Clark at Mer Island, Torres Strait, and recorded by him 

 as S. monacantha belongs to this species. In the key to the species of the genus 

 Stephanometra, monacantha (=protectus) was given as having P 2 much enlarged and 

 stilfened, usually more or less straight, ending distally somewhat abruptly in a stout 

 point, and composed of 11-15 (usually 12) segments of which the fourth-fifth are mark- 

 edly the longest; indica was given as having P 2 somewhat less enlarged and stiffened, 

 usually more or less strongly recurved, becoming very slender and delicate distally, 

 though not flagellate, and composed of 15-20 segments of which the fourth-fifth are
